Back when I was in college, I actually met a Holocaust denier. He and I got into a conversation, and he challenged me to "prove" that the Holocaust happened. My answer to him was "#### you. I'm not going to waste my time proving anything to you." Why should I? He was a ####### idiot, and a bigot as well.That's how I feel about the Birthers. Their motivation for this "inquiry" is, IMO, dishonest, sometimes even to themselves. They would never question Obama's birthplace if he was a white man with a traditional "American" name. Obama's answer to them should be "#### you." That's my response anyhow.So in answer to your question, Obama's "refusal" (if that's what it is, is not shameful, it's honorable. If I were he I would refuse to cooperate in anyway whatsoever.
